You're well towards your way to a promotion, keep up the good work (y)

I'm sure you're being sarcastic there.

That link that I just posted. It's about circumcision. Not the greatest topics of all I must admit but it's quite disgusting.

If you can't appreciate the boss's kindness then say goodbye to that promotion I was going to give you

Oooh, you're playing the take it or leave it game. What's the promotion anyway?

Please try this question :smile:

The gravitational potential energy of an astronaut, mass

, between the Earth and the moon is given by the equation:

When r=distance between the moon and the Earth.
When

, the astronaut is equally attracted to the moon and the Earth. Find an expression for x when this occurs.

This is a nice problem, and it's differential; [-GM_em/x^2]-[-GM_mm/(r-x)^2]

However, when you equate this to zero you get an issue! You can never have a value of x for which you divide the constants by to get zero! 1/x can never equal zero!

So your graph shoots off to infinite! The solution looks something like this.. (assuming an 80kg astronaut)

However, that would give a solution of around 6'800km. I'm not convinced your original equation was correct though.
The gravitational pull of something is equal to [GM_object]/r^2, so the point where the 2 attractions balance

[G*M_e]/r^2=[G*M_m]/R^2

Given G and the Masses are constant you could solve for R like that.

This may all be rubbish, but just my ideas. Sorry if this wastes your time!
